Yog ntsia thawv polish ib qho compound, sib tov , kev? nws yog a sib tov tseeb. Ntxiv rau qhov point, nws yog homogenous sib tov txhais tau hais tias tag nrho nws cov khoom sib xyaw ua ke. Cov khoom xyaw , qhov tseeb, tsis tuaj yeem raug cais los ntawm cov txheej txheem pom yooj yim.
Ib yam li ntawd, tib neeg nug, hom kev sib tov dab tsi yog ntsia thawv polish tshem tawm?
Ntsia polish remover yog qhov tseem ceeb a sib tov dej thiab tshuaj hu ua acetone. acetone ntau npaum li cas yuav tsum tau ua ke nrog cov tshuaj uas yog 10% acetoneto ua 30 oz ntawm 37% tov?
Tsis tas li ntawd, puas yog calcium carbonate ib qho sib xyaw ua ke? A heterogeneous sib tov yog ib qho uas muaj ob lossis ntau yam khoom. Nws yog non-uniform thiab cov khoom sib txawv ntawm cov sib tov tuaj yeem pom. Ib qho piv txwv yuav yog a sib tov ntawm xuab zeb thiab dej. Piv txwv ntawm cov tebchaw yog sodiumchloride (NaCl), hlau sulfide (FeS), calcium carbonate (CaCO3) thiab dej (H2O).
Qhov thib ob, yog mis nyuj sib tov heterogeneous?
Mis yog ib qho piv txwv ntawm a heterogeneousmixture . Cov khoom xyaw tuaj yeem muab cais ua ob (lossis ntau dua) cov khoom ntawm tus kheej los ntawm kev siv lub cev. Peb lub khob dej khov nab kuab sib tov vim peb tuaj yeem yooj yim cais cov dej khov los ntawm cov kua dej los ntawm kev pom.
Puas yog Cola homogeneous lossis heterogeneous?
Txhua qhov sib xyaw uas muaj ntau tshaj ib theem ntawm qhov teeb meem yog a heterogeneous sib tov. Qhov no tuaj yeem yog qhov nyuaj vim tias kev hloov pauv ntawm cov xwm txheej tuaj yeem hloov pauv qhov sib xyaw. Piv txwv li, lub unopenedsoda nyob rau hauv ib lub raj mis muaj ib tug uniform muaj pes tsawg leeg thiab yog ib tug homogeneous sib tov. Thaum koj qhib lub raj mis, npuas tshwm hauv cov kua.

Puas yog Oxygen yog cov khoom sib xyaw lossis sib xyaw?
Puas yog oxygen yog ib qho khoom sib xyaw lossis sib xyaw? Oxygen yog ib yam khoom. Nws yog tsim los ntawm tib hom atom, oxygen atoms (8 protons). Nws tshwm sim kom ruaj khov tshaj li molecules ntawm muaj pes tsawg leeg
Puas yog cov pa roj carbon dioxide yog qhov sib xyaw lossis sib xyaw?
CO2 yog lub npe hu ua carbon dioxide. Ib lub ntsiab yog ib yam khoom ua los ntawm ib hom atom. Cov tshuaj uas tsim cov khoom sib tov tuaj yeem yog cov khoom lossis cov khoom sib txuas, tab sis cov khoom sib tov tsis tsim cov tshuaj sib txuas. Cov khoom sib xyaw tuaj yeem sib cais rau hauv lawv cov khoom qub ib zaug ntxiv (kwv yees) yooj yim
Puas yog hluav taws xob yog cov khoom sib xyaw lossis sib xyaw?
Kev tshuaj xyuas cov ntsiab lus, cov khoom sib xyaw, thiab cov khoom sib xyaw Ionic Cov Khoom Siv Covalent Sib Nqus Sib cais rau hauv cov khoom siv hluav taws xob hauv dej kom muab cov kev daws teeb meem uas ua hluav taws xob nyob twj ywm zoo li qub molecule hauv dej thiab yuav tsis ua hluav taws xob
Puas yog Helium yog cov khoom sib xyaw lossis sib xyaw?
Helium atoms ib txwm muaj ob lub protons txhua, thiab hloov nws cov naj npawb ntawm cov protons yuav ua rau nws muaj qhov sib txawv tag nrho. Feem ntau cov khoom hauv peb lub ntiaj teb yog kev sib txuas ntawm cov ntsiab lus hu ua kev sib tov, nrog rau cov khoom sib xyaw ua ke hu ua cov tebchaw
Puas yog carbon dioxide yog cov khoom sib xyaw lossis sib xyaw?
Nws txhais tau hais tias muaj ib lub atom ntawm carbon thiab ob atoms ntawm Oxygen bonded ua ke ua ib tug molecule hu ua carbon dioxide. Ib qho molecule yog qhov tsawg tshaj plaws uas muaj peev xwm muab faib tau thiab tseem yog nws tus kheej thiab qhov sib tov yog thaum cov tshuaj tsuas yog sib xyaw ua ke xws li ntsev thiab kua txob
